I don't see anything in Preference that would do this out-of-the-box.
However, you could receive key events in your PreferenceActivity
subclass and dispatch it to the current (that would need to be defined,
too) preference.
Another way that comes to mind is using a dialog preference with a
slider, instead of a slider directly in the preference list... which has
the advantage of already having the concept of currently affected value.
You'd then receive key events in the dialog (sub)class.
( Regarding the device - are there still cars that can use those
DIN-sized radios? I thought this was a thing of the past, apparently not? )

A number of my custom preferences are of the'"Seekbar" variety. They
can be adjusted nicely on a touch screen device. However, our app is
no also being used on the Parrot Asteroid which doesn't even have
proper left/right keys (the scroll wheel emulated up/down).
I can map the media keys prev/next to left/right, so there is a
hardware workaround. I just don't know how to catch these key events
for my custom preference (without impacting the up/down paradigm) and
convert them into slider changes. I guess worst case I could override
the onClick event for the custom preference so that hitting the big
button would cycle through a few discrete slider settings.
Is it possible to override onKeyDown for a custom preference?
